DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of the present invention is now described with referenceto FIGS. 1 to 15. According to this embodiment, the present invention isapplied to an ergometer employed as an exemplary training apparatus.

FIG. 1 is a side elevational view partially showing the internalstructure of a training apparatus 1 according to the embodiment of thepresent invention.

As shown in FIG. 1, the training apparatus 1 comprises a body part 8, ahandlebar assembly 2 gripped by the user, a handle stem 4 rotatablysupporting the handlebar assembly 2, a saddle 5 provided on the bodypart 8 so that the user sits down thereon and pedals 11 rotatably set onthe body part 8 so that the user takes exercise by pedaling.

The body part 8 stores various elements such as frames 9 a to 9 d,loading means (not shown), a connecting mechanism connecting the loadingmeans with the pedals 11 and a crank set, various types of sensors andthe like. The frames 9 a to 9 d can be constituted of hollow metallicmembers, for example. The pedals 11, connected with the crank set, areconnected with the aforementioned connecting mechanism through the crankset.

The handlebar assembly 2 is rotatably mounted on the upper end of thehandle stem 2. As shown in FIG. 2, the handlebar assembly 2, formed in asubstantially C-shaped manner, for example, is mounted on the handlestem 4 through a holder 23. Referring to FIG. 2, the handlebar assembly2 has handlebars 20, handgrips 21 provided on ends of the handlebars 20to be gripped by the user and a pair of handle levers (operatingmembers) 22 manually operable by the user. The user can operate thehandle levers 22 by gripping the same with his/her hands respectively.

The handle stem 4 includes a base part 4 b connected with the body part8 and a movable part 4 a arranged on a side closer to the handlebarassembly 2 and inclinably coupled to the base part 4 b. The base part 4b and the movable part 4 a can be formed by hollow metallic members, forexample, and the base part 4 b is connected with the frames 9 c and 9 dof the body part 8 while the handlebar assembly 2 is mounted on theupper end of the movable part 4 a through the holder 23.

According to this embodiment, the user can adjust the angle of rotationof the handlebar assembly 2 with the first handle lever 22, whileadjusting the inclination of the movable part 4 a of the handle stem 4with the second handle lever 22. The user may alternatively operate thehandle levers 22 of the training apparatus 1 according to thisembodiment by a method other than the aforementioned manual operation.

Further, the user may adjust only the angle of rotation of the handlebarassembly 2 by operating only the first handle lever 22, may adjust onlythe inclination of the movable part 4 a by operating only the secondhandle lever 22, or may adjust the angle of rotation of the handlebarassembly 2 as well as the inclination of the movable part 4 a byoperating both handle levers 22.

The training apparatus 1 may alternatively be provided with operatingmembers other than the handle levers 22. For example, two types ofpush-type operating members may be set on the training apparatus 1 foradjusting at least either the angle of rotation of the handlebarassembly 2 or the inclination of the movable part 4 a. While theseoperating members are preferably manually operable, the user may treador push the operating members with his/her feet for operating the sameor may operate the operating members with both of his/her hands andfeet. When the user operates the operating members with his/her feet,the operating members may be arranged on step parts 10 a and 10 bdescribed later or on the bottom portion of the body part 8, forexample.

In addition to the adjustability of the angle of rotation of thehandlebar assembly 2, the inclination of the movable part 4 a of thehandle stem 4 is also adjustable as hereinabove described, whereby theuser can control the handlebar assembly 2 into various positions ascompared with a case where only the angle of rotation of the handlebarassembly 2 is adjustable. When the handle levers 22 are employed,further, the user can adjust the angle of rotation of the handlebarassembly 2 and the inclination of the movable part 4 a by simplygripping the handle levers 22 with his/her right and/or left hand,thereby easily controlling the position of the handlebar assembly 2.

Mechanisms for adjusting the angle of rotation of the handlebar assembly2 and the inclination of the movable part 4 a of the handle stem 4 arenow described with reference to FIGS. 3 to 11.

FIG. 3 is an enlarged view showing the handlebar assembly 2, the movablepart 4 a and a portion around the same. As shown in FIG. 3, a handlebarassembly angle adjusting part 15 is provided on the upper end of themovable part 4 a. With this handlebar assembly angle adjusting part 15,the user can adjust the angle of rotation of the handlebar assembly 2stepwise as shown in FIG. 3. Referring to FIG. 3, the user can adjustthe angle of rotation of the handlebar assembly 2 in a four-stage mannerin units of an angle θ1 (e.g. 30°).

FIG. 4 is a partially enlarged plan view of the handlebar assembly 2. Awire (control wire) 24 is arranged along each handle bar 20, as shown inFIG. 4. A stop part 25 is mounted on a first end of the wire 24, andconnected with an end of the corresponding handle lever 22. A couplingpart 27 is provided on a second end of the wire 24 as shown in FIG. 5,for coupling the wire 24 and an angle adjusting pin 26 with each otherthrough this coupling part 27.

The holder 23 holding the handlebar assembly 2 has a fixed part 23 a, arotatable part 23 b and angle adjusting holes 30 reaching the fixed part23 a through the rotatable part 23 b, as shown in FIG. 5. A housing 29having an internal space is set to be connected with the rotatable part23 b, and a spring 28 is arranged in the internal space of the housing29. The angle adjusting pin 26 has a large-diametral portion, and thespring 28 is set between the large-diametral portion and the innersurface of the housing 29 closer to an end thereof Thus, the spring 28can urge the angle adjusting pin 26 to partially reach the fixed part 23b, for fixing the position of the handlebar assembly 2.

When the user manually rotates each handle lever 22 from the state shownin FIG. 4 to that shown in FIG. 6, the handle lever 22 pulls the wire24. Thus, the user can contract the spring 28 while moving the angleadjusting pin 26 leftward as shown in FIG. 7. Consequently, the user canpull out the angle adjusting pin 26 from that of the angle adjustingholes 30 located in the fixed part 23 a, for rotating the handlebarassembly 2.

When the user thereafter releases the handle lever 22, the spring 28urges the angle adjusting pin 26 so that an end of the urged angleadjusting pin 26 automatically reaches that of the angle adjusting holes30 located in the fixed part 23 a. Thus, the handlebar assembly 2 isfixed to the holder 23 again in a state rotated by a desired angle.

As shown in FIG. 8, four angle adjusting holes 30 are provided atregular intervals along the outer periphery of each handle bar 20according to this embodiment. Therefore, the user can adjust the angleof rotation of the handlebar assembly 2 in the units of the angle θ1.The number of the angle adjusting holes 30 can be arbitrarily set, whilethe intervals between the angle adjusting holes 30 may be rendereddifferent from each other. The training apparatus 1 may be furtherprovided with an angular range regulation groove regulating therotatable angular range of the handlebar assembly 2 and an angular rangeregulation pin engaged into this angular range regulation groove, forinhibiting the handlebar assembly 2 from excessive rotation.

Referring again to FIG. 3, the user can also adjust the inclination ofthe movable part 4 a of the handle stem 4 in a multistage manneraccording to this embodiment. For example, the user can adjust theinclination of the movable part 4 a of the handle stem 4 in athree-stage manner in units of an angle θ2 (e.g. 10°). As shown in FIG.3, the movable part 4 a is rotatably coupled to the base part 4 bthrough a rotation axis 16. The lower end of the movable part 4 a is sotapered that this tapered portion and the base part 4 b opposed theretoform an angle twice the angle θ2. Thus, the movable part 4 a can beinhibited from excessive inclination.

FIG. 9 is a partially fragmented enlarged sectional view of the movablepart 4 a and a portion around the same. As shown in FIG. 9, the movablepart 4 a has a rotatable part 4 d rotatable with respect to the fixedpart 4 c fixed to the base part 4 b. The rotatable part 4 d is connectedwith the movable part 4 a, and rotatable about the rotation axis 16along with the movable part 4 a.

FIGS. 10 and 11 show the internal structures of the movable part 4 a andthe portion around the same. As shown in FIG. 10, a through hole isprovided to partially pass through the rotatable part 4 d, so that anangle adjusting pin 18 and a spring 19 are arranged in this throughhole. The spring 19 urges a large-diametral portion of the angleadjusting pin 18 toward the fixed part 4 c. A plurality of angleadjusting holes 17 are provided on the surface of the fixed part 4 c atintervals. Each angle adjusting hole 17, communicable with theaforementioned through hole, receives a first end of the angle adjustingpin 18. A second end of the angle adjusting pin 18 is connected with thefirst end of the wire 24 through a coupling part 31. The wire 24 isderived out from the movable part 4 a through a wire deriving hole 32,while a second end of the wire 24 is connected with the handle levers22.

In the state shown in FIG. 10, the first end of the angle adjusting pin18 is inserted in one of the angle adjusting holes 17, thereby fixingthe movable part 4 a to the base part 4 b. When the user manuallyrotates the handle levers 22 from this state, the handle levers 22 pullthe wire 24 for contracting the spring 19 and pulling up the angleadjusting pin 18 as shown in FIG. 11. Thus, the user can pull out theangle adjusting pin 18 from the corresponding angle adjusting hole 18,for rotating and inclining the movable part 4 a.

When the user thereafter releases the handle levers 22, the spring 19urges the angle adjusting pin 18 for automatically inserting an endthereof into another angle adjusting hole 17. Thus, the movable part 4 ais fixed to the base part 4 b again in a state inclined by a desiredangle.

As shown in FIGS. 1 and 3, the training apparatus 1 according to thisembodiment further comprises a control/display part 3 capable ofdisplaying various information and receiving various inputs, a supportpart 13 connected with the handle stem 4 for supporting thecontrol/display part 3, a mounting part 51 mounted with thecontrol/display part 3 and a connecting part 52 rotatable on the supportpart 13 with respect to the support part 13 for inclinably supportingthe mounting part 51 and the control/display part 3 with respect to thesupport part 13 and connecting the mounting part 51 and the support part13 with each other.

The aforementioned control/display part 3 comprises a screen fordisplaying various information and an interface for inputting variousinformation such as a working mode of the training apparatus 1. Themounting part 51 and the connecting part 52 are connected with eachother through a rotation axis 53. Thus, the user can incline thecontrol/display part 3 with respect to the support part 13 along withthe mounting part 51.

The connecting part 52 is connected with the support part 13 throughanother rotation axis 54. Thus, the user can rotate the connecting part52 about the rotation axis 54, for rotating the connecting part 52 onthe support part 13 along the surface of the support part 13. Thecontrol/display part 3 is connected with the connecting part 52 throughthe mounting part 51 and the rotation axis 53, whereby the user can alsorotate the control/display part 3 by rotating the connecting part 52.

As shown in FIG. 3, the connecting part 52 has a recess therein so thata ball plunger 55 is mounted on the support part 13 to reach the recess.The ball plunger 55 has a ball provided on the forward end and a springprovided in the inner part for urging this ball. A single or a pluralityof engaging holes are provided on the inner surface of the connectingportion 52 for receiving the ball of the ball plunger 55, so that theuser can fix the control/display part 3 on a desired position byengaging the ball in the corresponding engaging hole. The ball plunger55 and the engaging hole(s) are so set on the training apparatus 1 thatthe user can control the angle of rotation of the control/display part3. When the engaging holes are provided on three portions at intervalsof 90°, for example, the user can horizontally rotate the controldisplay part 3 in units of 90° in the angular range of 180°. The numberof and the position(s) for setting the engaging hole(s) are so properlyselected that the user can horizontally rotate the control/display part3 in a desired angular range.

The mounting part 51, the connecting part 52, the rotation axes 53 and54 and the ball plunger 55 constitute a control/display part movingmechanism 14 according to this embodiment. The user can not only inclinethe control/display part 3 but also rotate the control/display part 3 ina direction different from the direction of inclination with thiscontrol/display part moving mechanism 14, whereby not only the user butalso another person can easily visually recognize the control/displaypart 3. Consequently, a supervisor such as a kinesitherapist can easilycontrol the exercising state of the user.

As show in FIG. 1, the saddle 5 is mounted on the upper end of a seatpost 7. An auxiliary part 6 capable of partially supporting the body ofthe user is preferably provided in the vicinity of the saddle 5.Referring to FIG. 1, the auxiliary part 6 is uprightly provided at theback of the saddle 5, for supporting the loins of the user or portionsclose thereto. The auxiliary part 6, connected with the seat post 7, canbe constituted of a metallic pipe and a cushion, for example. Thecushion may be mounted on the upper end of a portion, such as theauxiliary part 6, for example, partially supporting the body of theuser. This auxiliary part 6 can assist the user to take exercise in astable state from the back.

As shown in FIG. 1, the training apparatus 1 according to thisembodiment further comprises a saddle height control mechanism 56provided on the body part 8 for controlling the height of the saddle 5and a saddle height control lever 12 allowing the user to drive thesaddle height control mechanism 56 with his/her foot.

FIG. 12 is an enlarged view of the saddle height control mechanism 56.As shown in FIG. 12, the saddle height control mechanism 56 has acoupling member 33 connected with the saddle height control lever 12, ajoint rod 35 connected with the coupling member 33, another couplingmember 36 connected with the joint rod 35, another joint rod 38connected with the coupling member 36, a locking member 40 connectedwith the joint rod 38, rotation axes 34 and 37, a spring 39 and a saddleheight control part 42.

The saddle height control lever 12 is preferably provided on a position,such as the bottom of the body part 8 or in the vicinity thereof,allowing the user to operate the same with his/her foot. Thus, the usercan operate the saddle height control lever 12 with his/her foot foreasily controlling the height of the saddle 5 with both hands.

The L-shaped coupling member 33 is rotatable about the rotation axis 34.The saddle height control lever 12 is connected with a first end of thiscoupling member 33. A second end of the coupling member 33 is connectedwith a first end of the joint rod 35. A second end of the joint rod 35is connected with a first end of the L-shaped coupling member 36; Thiscoupling member 36 is rotatable about the rotation axis 37. A second endof the coupling member 36 is connected with a first end of the joint rod38. A second end of the joint rod 38 is connected with the couplingmember 44. The coupling member 44 is fixed to the locking member 40,while a first end of the spring 39 is also connected with the couplingmember 44. The spring 39 is arranged oppositely to the joint rod 38 inrelation to the coupling member 44, and a second end of the spring 39 isconnected with part of the body part 8. Therefore, the user can urge thelocking member 40 to separate from the joint rod 38 with this spring 39.

As shown in FIGS. 12 and 13, the locking member 40 has a pair of outerplates 45, a rotation axis 43 coupling the outer plates 45 with eachother, a pair of inner plates 46, a coupling member 44 coupling theinner plates 46 with each other and polygonal bars 41 a and 41 b such ashexagonal bars mounted on the inner plates 46 at an interval. Thepolygonal bars 41 a and 41 b are arranged on both sides of the seat post7, so that the user can fix the position of the seat post 7 by bringingthe polygonal bars 41 a and 41 b into pressure contact with the seatpost 7 and the frame 9 a respectively.

An exemplary structure of the saddle height control part 42 is describedwith reference to FIG. 14. As shown in FIG. 14, the saddle heightcontrol part 42 has a pipe spacer 57 set between the seat post 7 and theframe 9 a, a pipe guide roller 58 rotatable along the outer periphery ofthe seat post 7, a holding member 48 holding the pipe guide roller 58through a rotation axis 47 and a fixing member 49 such as a screwconnecting the holding member 48 with a support mechanism. The supportmechanism, mounted on the outer periphery of the frame 9 a, can beconstituted of a top plate and a fastening member such as a bolt.

A method of controlling the height of the saddle 5 is now described. Inorder to release the seat post 7 from a state locked with the lockingmember 40 shown in FIG. 12, the user treads on the saddle height controllever 12 for rotating the coupling member 33 clockwise. Thus, the jointrod 35 moves toward the coupling member 33, thereby also rotating thecoupling member 36 clockwise. The joint rod 38 moves toward the couplingmember 36 due to this clockwise rotation, thereby rotating the lockingmember 40 clockwise. Consequently, the polygonal bars 41 a and 41 bseparate from the seat post 7, thereby releasing the seat post 7 fromthe state locked with the locking member 40. In this state, the uservertically moves the saddle 5 with both hands or the like, therebyvertically moving the seat post 7 in the frame 9 a. At this time, theuser can smoothly move the seat post 7 in the frame 9 a due to theprovision of the aforementioned pipe guide roller 58. The user releasesthe saddle height control lever 12 when the vertically moved saddle 5reaches a desired position. Thus, the user can automatically lock theseat post 7 with the locking member 40 through operations reverse to theabove.

As shown in FIGS. 1 and 15, the training apparatus 1 according to thisembodiment further comprises the step parts 10 a and 10 b provided onportions of the body part 8 located in the vicinity of the handle stem7. The training apparatus 1 may alternatively be provided with a singletype of step part or at least three types of step parts in place of thetwo types of step parts 10 a and 10 b shown in FIGS. 1 and 15.

The step parts 10 a and 10 b can assist the user to get on and off thetraining apparatus 1. It is also possible to ensure a space above thestep parts 10 a and 10 b, as shown in FIG. 1. Therefore, the user caneasily get on and off the training apparatus 1, which is effective fortraining of not only a healthy young person but also a middle-agedperson or for rehabilitation of a sick person.

Referring to FIG. 15, the step parts 10 a provided on both sides arelocated on lower positions while the central step part 10 b is locatedon a higher position. The central step part 10 b is so located on thehigher position that the user can get on and off the training apparatus1 from either side of the training apparatus 1 while the degree offreedom in setting of the training apparatus 1 is improved.

While the height of the step parts 10 a provided on both sides is abouthalf the height of the central step part 10 b in FIG. 15, the user canarbitrarily set the relation between the vertical positions of the stepparts 10 a and 10 b. When each of the step parts 10 a and 10 b is formedby at least three tread-boards and reduced in height, the trainingapparatus 1 can conceivably be rendered further effective forrehabilitation of a person advanced in years or a sick person.

The present invention is effectively applicable to a pedal trainingapparatus allowing the user to take exercise by pedaling.
